I thought that you were the tech director for Autolite, At least that is what you said in your one other post on this forum. The site says nothing about filtration. It just states media size in Square inches and number of pleats. Plenty of people use fram and like them. I for one will not use fram. My truck came with an AC delco filter and that is what it gets replaced with. I will also not use Autolite plugs. I simply do not like them. It is just my personal preference. Nothing against the company.
